This generates useful telemetry for assessing the health of clients talking to Consul over HTTP. It rolls up telemetry about endpoints by using this basic structure:
consul.consul.http.<verb>.<parts>
<verb>
is the HTTP verb, and<parts>
is based on the path that is registered for each endpoint. It won't contain any specific parts of the path like service names or key names. For paths that have a variable part, a_
placeholder will be added.Here's some example telemetry with this patch active:
You can see the KV example, where we have
consul.consul.http.GET.v1.kv._
. This prevents leaking sensitive information and also prevents an explosion of telemetry.
